Pins 8346, loosen fan and viscous assembly from
water pump (Fig. 69).
(7) Remove fan and viscous assembly.
(8) Disconnect electrical connector for fan mounted
inside radiator shroud.NOTE: Transmission cooler line snaps into shroud
lower right hand corner.
(9) Remove crankshaft damper bolt.
(10) Remove damper using Special Tools 8513
Insert and 1026 Three Jaw Puller (Fig. 70).
INSTALLATION
CAUTION: To prevent severe damage to the Crank-
shaft, Damper or Special Tool 8512, thoroughly
clean the damper bore and the crankshaft nose
before installing Damper.
(1) Align crankshaft damper slot with key in
crankshaft. Slide damper onto crankshaft slightly.
CAUTION: Special Tool 8512, is assembled in a
specific sequence. Failure to assemble this tool in
this sequence can result in tool failure and severe
damage to either the tool or the crankshaft.
(2) Assemble Special Tool 8512 as follows, The nut
is threaded onto the shaft first. Then the roller bear-
ing is placed onto the threaded rod (The hardened
bearing surface of the bearingMUSTface the nut).
Then the hardened washer slides onto the threaded
rod (Fig. 71). Once assembled coat the threaded rod's
threads with MopartNickel Anti-Seize or (Loctite
No. 771).

lbs.) torque. Tighten oil pan bolts to 24 N´m (215 in.
lbs.) torque.
(10) Remove the vibration damper bolt and seal
installation tool.
(11) Install vibration damper.
(12) Install water pump and housing assembly
using new gaskets (refer to Group 7, Cooling Sys-
tem). Tighten bolts to 41 N´m (30 ft. lbs.) torque.
(13) Install power steering pump (refer to Group
19, Steering).
(14) Install the serpentine belt (refer to Group 7,
Cooling System).
(15) Install the cooling system fan. Tighten the
bolts to 23 N´m (17 ft. lbs.) torque.
(16) Position the fan shroud and install the bolts.
Tighten the bolts to 11 N´m (95 in. lbs.) torque.
(17) Fill cooling system (refer to Group 7, Cooling

TIMING CHAIN
REMOVAL
(1) Disconnect battery negative cable.
(2) Remove Timing Chain Cover. Refer to Timing
Chain Cover in this section for correct procedure.
(3) Re-install the vibration damper bolt finger
tight. Using a suitable socket and breaker bar, rotatethe crankshaft to align timing marks as shown in
(Fig. 52).
(4) Remove camshaft sprocket attaching bolt and
remove timing chain with crankshaft and camshaft
sprockets.
INSTALLATION
(1) Place both camshaft sprocket and crankshaft
sprocket on the bench with timing marks on exact
imaginary center line through both camshaft and
crankshaft bores.
(2) Place timing chain around both sprockets.
(3) Turn crankshaft and camshaft to line up with
keyway location in crankshaft sprocket and in cam-
shaft sprocket.
(4) Lift sprockets and chain (keep sprockets tight
against the chain in position as described).
(5) Slide both sprockets evenly over their respec-
tive shafts and use a straightedge to check alignment
of timing marks (Fig. 52).
(6) Install the camshaft bolt. Tighten the bolt to 68
N´m (50 ft. lbs.) torque.
(7) Check camshaft end play. The end play should
be 0.051-0.152 mm (0.002-0.006 inch) with a new
thrust plate and up to 0.254 mm (0.010 inch) with a
used thrust plate. If not within these limits install a
new thrust plate.
(8) Install the timing chain cover.
CAMSHAFT
NOTE: The camshaft has an integral oil pump and
distributor drive gear (Fig. 53).
